What is Angiography?
Angiography is the most frequently performed test in cardiovascular surgery and gives us the most reliable information.
Angiography shows the width, length, diameter of the vessels, the places of stenosis, the severity of the stenosis of arteries of the heart. The procedure is performed by entering vascular system from the arm or the groin and giving a dye to the arterial three of the heart. Thus we learn and see if the vascular patency continue after the stenosis or how much space does it occupy in full stenosis, are there open vessels after the full occlusion? Angiography is the name of the examination that shows us many such parameters with crystal clarity.
Angiography is basically a painless, bloodless procedure. It is not an operation.
It takes about 10 minutes. During the procedure, we enter thearm or groin arterial vessel with long 1-1.5 meter hoses with the thickness of special spaghetti pasta.
We forward angiography catheter from the arm to the orifice of the heart vessel by sending a tube through the vessels of the arm, and we give an external dye right at the mouth of the vessels that feed the heart. This dye is a dye that appears black under radiation, that is, when the x-ray film is taken, and simultanously when we give the dye, that dye fills the vessels of the heart and we shoot the films 4-5 times a second one after the other. Here, if the black-looking paint we give during this image fills all the vessels of the heart well, it means that the paint has penetrated well everywhere, that is, the vessels are open, but if this paint does not enter certain important places that we expect, if there is no black color there, we say that the vessel is completely clogged and the dye cannot enter here.
